Answer 1

Answer:

formula for strength of KMno4 solution???

Explanation:

To determine the strength of a given potassium permanganate solution against a standard ferrous ammonium sulfate (Mohr's salt) solution.

The strength of and molarity of given KMnO4 solution is found out as 2/y x 31.6 g/l and N/5 moles/liter, respectively.

Answer 2

Answer

Correct option is

A

0.02M

MnO
